DevRev CTO Ahmed Bashir Says Engineering Team Has Fully Shifted to Codex and Dropped Cursor
DevRev Chief Technology Officer Ahmed Bashir describes the process by which his engineering team naturally shifted to Codex and abandoned Cursor after exploring multiple coding tools, arguing that developers choose tools based on actual experience rather than marketing.
In a customer case study published by OpenAI, DevRev Chief Technology Officer Ahmed Bashir described a specific tool migration process: his engineering team fully shifted to Codex and dropped its previously held Cursor licenses after exploring multiple coding tools. Bashir emphasized that this shift was not mandated by management but was the result of engineers independently comparing options and naturally converging on a choice.
Bashir attributed this process to developers' direct judgment regarding tool quality. He stated, "Developers are really just looking for the best tool, and you can't fool them." He noted that no one in the team raised objections to continuing with Codex, believing it offered "far and away the best experience." This assessment stemmed from his observation as a technical leader of the team's actual usage patterns, rather than from independent evaluations.
At a broader AI architecture level, DevRev uses GPT-6.1 Sol to power its Computer and Operator products, which are designed for enterprise customer service and internal operations. Bashir described his core criteria when selecting models: correct reasoning capabilities, trustworthy alignment levels, and most critically, latency that meets business requirements. He stated that GPT-6.1 Sol performed well in DevRev's self-built Enterprise-Bench evaluation, which tests models under conditions where data exists in multiple versions, information is scattered across different systems, and access rights depend on user roles. Bashir said the model "strikes the balance perfectly."
It should be noted that this is a customer case study article published by OpenAI, and DevRev's Enterprise-Bench evaluation results have not been independently verified by third parties. Bashir's discussion of developer judgment is his interpretation of a single company's experience and cannot be directly generalized as a universal behavioral pattern for the entire developer community. The decision for Codex to replace Cursor occurred within a North American AI customer service company, whose scale, technology stack, and business scenarios differ from those of other organizations.
